The invention is attributed to the field of foldable and bendable greenhouses. The convex-greenhouse consists of a rectangular shape frame (2), trapezium (2) or half-ellipsis arcs (3) bound by flexible non-stretching strings (4). The stiffness of the framework is achieved by stretching strings bound to arcs on the frame, the bent unrestricted ends of which are embedded and lean inside holes of the same frame. The framework is covered by a transparent film, the edges of which are fixed to the frame. The convex-greenhouse folds when the ends of the arcs are pulled out of the holes. |
